At one point, Kardashian, Grutman and another one of their pals enjoyed some "barefoot shopping."

One night earlier, Kourtney was spotted at Komodo, a local high-end Southeast Asian restaurant, to help kick off Grutman's 36th birthday festivities. They continued their celebrations at STORY nightclub, where Kourtney assisted DJ Cedric Gervais on the turntables.

In typical Kardashian fashion, the brunette beauty documented the night over social media, including a mirror selfie taken with BFF Larsa Pippen and a few of their other friends. Check out that tiger-printed dress!

Grutman later shared a pic from their outing to his own Instagram account, writing, "What a night. Thank You so much to everyone that made it so special for me."
